Total thyroidectomy and parathyroid autotransplantation for radiation-associated thyroid cancer

In seventy patients with nodular thyroids and a history of radiation exposure, total thyroidectomy disclosed a 54% incidence of carcinoma; more than half of them had cervial node metastases; four had distant metastases. Fourteen patients required radical neck dissection. The carcinoma was multicentric (both lobes) in 45%. In four patients the carcinoma was found in the lobe contralateral to the one containing the palpable nodule. These findings support the advocates of total thyroidectomy for patients with a nodular thyroid and a history of radiation exposure, provided this operation can be performed with a low incidence of recurrent nerve palsy and hypoparathyroidism.
